Medicare Part D Coverage Gap (“Donut Hole”)
Medicare Part D plans have a Coverage Gap, which is a temporary limit on what your drug plan will pay for prescription drug costs.
If you do not receive a subsidy such as Extra Help from Medicare, or aren’t enrolled in a plan that offers additional Gap coverage,
the combined amount you and your Part D plan spend on your Medicare Part D costs (not including premiums),
determines if and when you will reach the Gap. For 2018, that combined amount is $3,750.
While in the Gap, you will pay 44% of the cost for generic drugs, and 35% of the plan’s cost for brand drugs in 2018.
You leave the Gap when you alone (not what the plan spends) spend a total of $5,000 in 2018. You then enter the ‘Catastrophic Coverage’ stage, where the cost of your prescriptions are usually lower.
